As the result of many contributions to the study of the visual system the main features of its pathway within the brain have been well established. But the question of bilateral cortical representation of macular vision has not been satisfactorily settled, and it is with this problem and with the course of the geniculocalcarine radiation in man that this communication deals.
Study of the defects of the visual fields in patients who have undergone radical extirpation of carefully charted areas of the occipital and temporal lobes has led us to certain definite anatomic1 conclusions. The extirpations were done for the removal of cerebral cicatrices in cases of focal epilepsy. Because of this circumstance there was opportunity for considerable study and comparison before and after operation. In many of the published reports anatomic conclusions have been drawn from observations on cases of brain tumor, in which the normal structure may
